Genes affected

VWF (HGNC:12726): (von Willebrand factor) This gene encodes a glycoprotein involved in hemostasis. The encoded preproprotein is proteolytically processed following assembly into large multimeric complexes. These complexes function in the adhesion of platelets to sites of vascular injury and the transport of various proteins in the blood. Mutations in this gene result in von Willebrand disease, an inherited bleeding disorder. An unprocessed pseudogene has been found on chromosome 22. [provided by RefSeq, Oct 2015]

ACMG classification

Verdict is Pathogenic. Variant got 10 ACMG points.

• PM1: In a domain VWFA 2 (size 167) in uniprot entity VWF_HUMAN there are 44 pathogenic changes around while only 6 benign (88%) in NM_000552.5
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, VWF
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.988
• PP5: Variant 12-6018877-A-C is Pathogenic according to our data. Variant chr12-6018877-A-C is described in ClinVar as [Pathogenic]. Clinvar id is 304.Status of the report is no_assertion_criteria_provided, 0 stars.
